Answer 1

The correct option is E A- 5, B - 4, C - 1, D - 2

The example of aerobic bacteria is Azotobacter which requires oxygen for survival. It also plays an important role in the Nitrogen cycle.

The example of cyanobacteria is Aulosira, which is a photosynthetic bacteria.

Casuarina is the genus of nitrogen-fixing plants which helps to increase the nitrogen percentage of soil by the help of nitrogen-fixing bacteria called Frankia.

The tropical grasses contain the nitrogen-fixing bacteria named azospirillum.

Correct Answer is E.
